i own a 2006 STi and im' thinking about upgrading the vf39 im' goin for something bolts' on and after doing a little research im going for the FPred turbo! what should i expect of this turbo? my goal its' to make a 400 awhp car! i already got a 320 awhp cause i just got protune and gave me this numbers but u think with this turbo i'll be in those numbers??

So tell me this, what mods do you already have that give you 320 whp? Are you sure you aren't talking crank hp? I'm not aware of anyone around here that has those numbers with the stock turbo, even with tuning. Guys running with a 20g, fmic, tbe, fuel pump and other supporting mods are getting there only with a race gas tune. I'm confused.

If your only after 400whp, then I'd be looking at the GT30R rotated or the Green if your going low cost. FPRed is more suitable for 450+whp but has more lag. Still a decent turbo. Have one sitting on my dining room table right now...

Now I understand how you got those numbers, and that it was on a dynojet. We've got a mustang around here. You always get lower numbers on a mustang than a dynojet.

Hopefully this weekend. All Reds come with the 7cm these days. If you can find a 8cm housing (pretty rare), that would be the ticket. Somebody was selling a SZ49 8cm turbo and I thought about buying it and swapping the housing.
